(see Fig. 13), help seat the roll and tohold endlates' A and arings'of the rolls 1 and 1,with inward] projectingpins a, 0', against which By.v drawing its stub-shaft 1 outward,

either. roll can be=instantly disenga ed from its bearings andeasilyremoved. Thus the roll can be 'put in or out of position rapidlyand easily without any endwise adjustment of the-roll, and cannot bedisplaced except by first ulling'stub-shaft 1 outward by hand, whichaction is resisted'by spring 1, which is suiliciently powerful toovercome sprin 1 but as soon as shaft 1 is disengage from journal-seat1, spring 1' draws Journal-pin 1" into the roll, so that there are noprojectin journals at either end of the roll, and by tins making therolls with what we call disappearing journals the lattcr are protectedfrom in ury while the roll is out of the machine, and the removal andreplacement of each roll is facilitated. The construction of the rollsforms one feature of the invention.

The roll driving mcoham'sm-lllechanism is provided for driving eitherroll 1, 1, from the driving shaft, but only one roll is driven at atime, so that when one roll winds, the other trails unwinding. Mechanismis also provided so that both rolls are free of the driving mechanism,except during the time that they are being actually driven.

The roll 1 can be driven by gears 2", 2 2, 2, see Figs. 3, (l, 7, fromthe driving shaft 2, while the roll 1 can be driven by gears 2, 2', 2',from the same shaft. The ears 2 and 2' are res )ectively fast on the scoves in which the stub-shafts 1 that. engage the respective rolls 1 1are mounted. lhe gears 2" aml 2", are both loose upon the shaft 2, arearranged adjacent to each other between the plates A, B, and arerespectively provided on their op osed faces with clutchmembers 2", 2',see ig. 12 ada )ted to be engaged b a sliding clutch-mam ier 2 splinedon sha t 2, and havin its opposite ends adapted to engage the cntch-members 2", 2, respectively, it moved into engagement therewith;and of course when locked to one gear the other is free, consequentlybut one roll 1, or 1', can be positively driven at one time. Now shaft 2as a driver rotates intermittently but always in the same directionactuated intermittently b the spring 4, which exerts upon said rivinshaft the same amount of force in each period of actuation (as willhereinafter be explained). But it is obvious that to wind the ribbondownward on roll 1' requires less work than to wind the ribbon upward onroll 1. And this difference-in work considered in mechanics as thegravitation factor, amounts from plate C. The side are provided,adjacent the.

to twice the weight of that part. of the ribbon between the rolls,multiplied by the distanee of travel, where the radii of both rolls areequal; and in large machines of this type, this factor mightnecessitatea dillerence of fift per cent. or more in the Winding power of tie tworolls, or enough to render such machines impracticable, withoutv somemeans of compensation in the machines. And in all machines of this typelarge enough to make this gravitation factor con siderable, we havefound that the power required for winding the ribbon upward on roll 1,when applied to roll 1 for winding the ribbon downward, causes parts ofthe machine to move too rapidly and makes the ribbon go downward with alunge instead of moving as it should. And this lunging movement of theribbon downward not only interferes with the normal operation of theElungers 0 and 9", (hereina' tcr described),

ut it also gives roll 1, which is then trailing idle, a pull so quickand strong that, by the momentum thus acquired, roll 1 rotates too' fardetrimentally unwinding too much ribbon at a time. Com ensation for thisravitation factor, there ore, was found to e necessary. To meet theconditions, then, a difference of torque-leverage in the two rolls wasfound to be practicable, as may be seen in the present model from whichthe submitted drawings were made. And in this model, the winding powerrequired to wind the ribbon downward normally on roll 1" is abouteighty-three per cent. of the winding power required to wind the ribbonupward normally on roll 1; M1 adequate compensation of this difference1.- effected in part, by the perforated ribbon and its accessories incontrolling the extent of roll movement (to be fully explainedhereinafter), and in part by making the torque-leverage between d rivingshaft 2 and the surface of roll 1 ditlerent from the tor ire-leveragebetween driving shaft 2 and tie surface of roll 1", (to be fullyexplained hereinafter). While this might be done by making roll 1 ofless diameter than roll 1, or gear 2 of less diameter than gear 2, wehave preferred to make gear 2 larger than-gear 2' (see Figs. 6 and 7).Thus roll 1" gets a less winding power than roll 1; and itscorresponding excessive extent of roll-movement from one actuation ofthe spring 4", is cut short and compensated in the operation ofthcperforated rihbon and its accessories in controlling the extent ofribbon movement at each actuation of the spring 4" (as will be fullyexplained hereafter). Therefore, the ribbon and its accessories abovementioned in combination with the difference in said torque-leverage,constitute a complete means in the machine of compensating forgravitation factor of the' ribbon. Owing to the diil'erence of one idlegear wheel in the gear-trains to roll 1 lit) driven'in': oppositedirections, from shaft 2,

whichirotates. .always in one direction.

Mechanism is provided whereby the clutchmember'2E can -beshifted intoengagement Witheither' clutch-member. 2 or. 2', and whereby it canbeautomatically shifted so as-toreverse the .windin' of the ribbon S,-these mechanisms weI-wi I explain hereafter.

"1 'he..-means 'fOrJoPerating' the driving shaft 2.+On the end of'shaft2, see Figs. 3, 17, adjacent plate 0, is a loose pinion 2" providedQwitha clutch-member 2", opposite a sliding-clutch-member 2 splined on shaft2, and normally pressed toward member 2 by a spring 2'. Theclutch-member 2 is held out of engagement, normally, with member 2" bymeans of a finger 2 on a lever 2, pivoted on a bracket C attached toplate C, said finger 2 engaging an annular groove in the clutch-memberas shown. The

' ong arm of lever 2 passes through a slot in plate C, and past a do 2'pivoted on a stud C on late C, an controlled by a spring 2 whichnormally holds the dog in position to en age lever 2 and hold it in suchposition t at clutch-member 2 is kept out of engagement withclutch-member 2, consequently the shaft 2 is free of the driving meansuntil the clutch-members are engaged. The inion 2" meshes with a segment3, see FE 4, fixed on a rock-shaft 3 which is provi ed with an arm i3connected to a hm er 3 working in an oil dash-pot 3 0 or inaryconstruction, adapted to regulate the movement of the se ment 8. Andsaid rock-shaft is also rovi ed with an arm 3' connected by a lin c 8'to an arm 4 on a main or setting shaft 4 which is journaled in the endplates A and C as shown, and said arm 4 is, moreover, connected to oneend of a stout helical spring 4", the other end of which is fast to a inD" on late D. When the shaft 4 is rocized in the irection to tensionspring 4", se ment 3 turns the pinion 2" idly on shaft but just ast-he'segment about reaches the limit of its downward, or setting,stroke, a pin 3 on link 3', strikes the tail of dog 2' and causes it torelease lever 2", whereupon spring 2" throws clutch-member 2 intoengagement with clutch-member 2" thus lockmg the pinion 2" to shaft 2,and consequently when the segment 3 makes its return movement under theimpulse of sprin 4", the shaft 2 will be rotated, and the roll 1, or 1-(whichever is then geared up to shaft 2).,'will be rotated 11 certainextent. About the end of the return s ring-actuated movement-of thesegment (and the .end of each roll-driving operation) the clutch-member2 is automatically disengaged from inember 2" and locked open bydog-2"'the disen agement of the clutch as effects i by the ollowingdevices: To the inner side of plate C see Figs. 3, 16, 17 is attached aguide C in which plays a rod 3" ivotally connected at its rear end tothe owe r end of an oscillating lever 3' pivoted on a stud C attached toplate C, and provided with a controlling spring 3 which normallyncts tothrow the lower end of the lever forward, and push rod 3 forward intoengagement with the end of lever 2. In the plate C, near shaft 3", isfixed a post 3 against which is braced a spring 3 coiled around C,adapted to actuate arm 3 in one direction (Fi 16). The lever 3' islocked, when the r0 3" is retracted, by a dog 3 pivoted on a stud C onplate C above the lever and having a tooth adapted to engage a notch 3in the rounded upper end of lever 3' as shown, said dog being pressedinto engaging positiori by a spring 3'. The dog is caused toautomatically release lever 3' at the roper moment by the followingdevices, which form part of the sheet controllin and guiding deviceshereinafter describe Pivoted on stud C beside lever 3, is a second lever3 whose upper end is cam-shaped and adapted to engage a depending finger3" on dog 3, so as to cause the dog to release lever 3 when lever 3makes a predetermined extent of movement, (controlled by the ribbon ashereinafter explained.) The lower end of lover 3 is pivotally connectedto a rod 5) lying beside and parallel with rod 3". Rod 9 we willhereinafter describe in connection with the sheet-controlling andguiding devices. The rods 3" and 9 are provided with pins 3", 9, whichare ada ted to be engaged by arms 3', 3" on rock-siaft 3, and when thesegment 3 is rocked so as to tension spring 4", the rods 3 and 9 aredrawn backward, the action leaves the clutch-member 2 under the controlof dog 2', and as soon as the dog is tripped by pin 3*, as described,spring 2', will close the clutch 2 and thus siaft 2 will be operated bythe segment. When rod 8* is drawn backward, it is locked by theengagement of do 3, with lever 3', but the lever 8 moves fi irward asfast as the arm 3' will allow it until its forward and reaches theribbon S which arrests its further forward movement until the arrival ofan opening a in the ribbon S, through which rod 9 at once plunges,allowing arm 8 to complete its predetermined forward movement, then itscam-shaped upper end trips the dog 3* and releases rod 3 which springsforward, striking the end of lever 2 disengaging clutch-member 2" frommember 2, and thus freeing the shaft 2 from the action of spring 4", andthe segment, and so cutting off the motivepower from the rolls 1, or 1,until the shaft 4 is again rocked to put spring 4" under tension asabove descrlbed. By this arrangement it will be noted that theclutch-mem or mcr against the gong.

2 is both engaged and disengaged quickly from member 2, and is held outof engagement except during the exact period of time it is desired todrive the shaft 2 positively. So that We are enabled'to give a certainpre determined extent of revolution to either roller at each operationof shafts 4: and 2.

The audible aig'nalr-Each time the rolldriving devices are set inoperation an alarm can be sounded by the following means, so that theoperator will know that the device has properly worked, and theattention of passengers may be directed to the machine; On the segment 3see Figs. i and 18 is a pin 3 which projects through aslot in the'side-plate D, and engages a notch in the free end of an oscillatinglever 33* pivoted on a stud D attached to plate I). On'this stud besidelever 33 is pivoted a plate 3 provided with an arm 3 carrying a hammer 3adapted to strike a gong 3 attached to the side-plate as shown, and thusgivean audible signal. A spring 3 is ar runged to rock the plate andthrow the ham- The hammer is cocked by the downward movement of lever 33by means of a dog 13 pivoted on lever 33*, and adapted to engage a notch3 in the plate 3, and rock the plate the lever descends, until the dogis tripped by striking a pin D on plate D, whereupon the hanuner isthrown forward by the spring and the gong is sounded. The dog 13 iscontrolled by a spring 13.

T 11v vncn-hrmthrn. for shifting the roll drining rv/u/ph.As abovestated, either roll 1 or 1 can be positively driven from shaft 2, bymeans of the clutch Q and its actuating and controlling mechanism whichhas been adapted to shift said clutch 2 so as to drive positively eitherroll 1 or l" when shaft 2 is driven in the normal operation of theentire machine. Said actuating and controlling mechanism and itsfunctions in operation are as follows :-The clutch 2, Figs. 3 and 12,has an annular groove engaged by one arm 5 of a bell-crank lever pivotedon a bracket A g1 plate A. The other arm 5 of said bell-crank leverextends through a slot in plate A; and is notched at its end where it isloosely engaged by the lower end of a swinging lever 5, Figs. 3, l2, and10, loosely sleeved on a short rocloshaft (3 projecting through plate A.The lower end of lever 5 is adapted to be actuated forward by means of aspring 5 Fig. so as to move and hold the arms 5 and 5 in such a positionthat clutch 2, Will be pushed on its spline into engagement withclutch-member 2, and there held so that the lower roll 1 will bepositively rotated when shaft 2 is driven by the segment 3. ()n theother hand, when the lower end of-lever 5 is actuated backward againstthe spring 5' and against the arm 5, :tar enough toshift the arms 5, 5

so as to slide clutch 2 out of? engagement with clutch-member 2 and intoengagement with clutch-member 2, the position for positively rotatingroll 1 from shaft 2 said clutch 2 will be duly held in said position(see dotted lines, Fig. 12) by means of a catch 5 journaled on a stud Aon plate A, and having a notch adapted to engage a pin 5' on the side ofthe upper end of lever 5 as seen in Figs. 8, 9, 10, and 11. The coactingmeans for causing these two movements of clutch 2", are asfollowsz-iiigidly fastened to rock-shaft 6, beside lever 53, is a lever6, the lower end. of? which is; connected by a hinge joint to a rod 9similar to the rod 9 above described. And in the upper end of said lever6* is fixed a stud G Figs. 9 and 10) on which is journaled a dog 6"which swings in the same plane as the lever 5. And, (log 6*, by means ofa spring 6 (Fig. 9) coiled around stud it, is always pressed downtoward. the upper edge of lever 53. Now, if we suppose the lower ends ofboth levers 6 and 5 are in their extreme forward positions, then thelong pawl-like nose 6" of the dog 6" will be resting on the upper ledgeof lever 5, all as shown in Fig. 10; and bell-crank lever 5-5"' will beresting with its notched arm 5 fully forward, and its arm 5 will beholding clutch 2 in mesh with clutch 2 as shown in the solid lines ofFig. 12. Under these mnditions, it we operate the machine normally,rock-shaft 6 will swing the lower end of lever 6 backward in its fullstroke. And in the consequent forward movement of dog 6". the nose 6"will glide down into the non-h .3 where it. will soon meet the uprightside of said notch, as shown in Fig. and will finally push the upper endof lever 5" all the way forward. This movement forces the lower end ofis or 5 backward so that it overcomes the spring 5 and pu hes back thenotched end of arm 5* (Fig. 8" causing bell-crank lever 5--5 to swing soas to slide clutch 2 from clutch-member 2 into mesh with olutch-i'nember2 the position for op to keep the clutch in mesh with the" clutch-memberso long as roll 1 is to be positively driven, as shown in liig. S and 1nthe dotted lines of Fig. 12. Now. to shiftclutch 2 out of mesh withclutch-member 2 and back into mesh with clutch rnember'ii at apredetermined, time, it necessary to 133 I release lever 5, or in otherwords, to lift. the

catch 5 away fron pin 5; and this is effected in the. following way--11]the head of dog 6, and reaching out toward lever B, is fixed a pin (i 8,9. l0, and ti; and on the outer end of stud X is journalcd a longwedgeshaped can] ti rear-hing out over pin t3" and liavin a finger omerlyinn a pin A on plate A, by which pin the downward movement of saidcam 43* impelled by spring 6, Fig. i}, is normally arrested. There is,also, in the head of dog t'i' a pin 2" st's'ulding out o't'er the lowerpm i of catch 5", wnile the upper part of cati'h is a coin finger 5reaching alii ug-siiile dog (3 in a. osition to be engaged by pin (3whenever pin i moves up our Mil iii to relive: 'he member if from pinfind in opera ire connection with these parts. we should also noticeiliat. rccleelial'i (i, Fig. 3 is jourualed in plates A. and B; andthat; armm 'l the end of said rotrlc-shntt just inside of pla' l"). iscoiled a snriug (3 b plate B.
